sTovE- DRUM.

SPECIFICATION forming part of Letters Patent No.365,391, dated June 28, 1887. Application filed October 23, 1886. Serial No. 217,053. (No model.)'

To aZZcvhom it may concern.-

Be it known that I, CHARLES A. KUPEER, a citizen of the United States, residing at Burlington, in Des Moines county, State of Iowa, have invented a new and useful Improvement in Stove Drums, of which the following is a specification.

My invention relates to improvements in stove-drums in which an ordinary drum operates in conjunction with a pipe-secti0n so placed in the inside of this drum that its ends shall be supported by and rest in conduits formed by plates suitably attached to the ends of the drum; and the object of my invention is to furnish a drum which shall distribute the greatest possible amount of heat in a simple manner. I accomplish this by the mechanism illustrated in-the accompanying drawings, in which Figure 1 represents a vertical cross-section of my invention. Fig. 2 represents an open end view of drum A, showing conduit formed by plate F.

' Similar letters refer to similar parts throughout the several views.

In the drawings, A represents an ordinary drum, preferably round in shape. Through drum A passes the pipe-section B, so that the drum A shall sit at right angles upon pipe B, as illustrated in the drawings. That part of pipe B which is within drum A has near the bottom of the drum A the opening 0. Right above the opening 0 there is in pipe 13 the damper D, having handle (I, by means of which it is operated.

Above damper D and at right angles with pipe B there are fastened to said pipe B the pi pesections E and E insuch a manner as to be in direct communication with pipe B.

communicate with one of these conduits, as

illustrated in the drawings.

Above drum A there is another damper, G, in pipe B.

The operation of my invention is as follows: When damper. D is closed the heated air and smoke pass through opening 0 into drum A and around pipesections E and E to the top of the drum A. At the top the air and smoke will pass into the conduits formedby plates F and F and from here into pipesections E and-E, respectively, and then back into pipe B, above damper D, and out. Thus the heated air and smoke passing from the stove-pipe into the drum is in its circulating motion through my improved drum constantly in direct contact with the surface of drum A, thereby furnishing the greatest possible advantage for the circulation and radiation of heat. If a direct draft be required, the damperD is opened, and in that case there is a free passage for the smoke up pipe B.

. What I claim as my invention, and desire to secure by Letters Patent, is- An improved stove-drum comprising the drum A. the pipe B, having opening (3 and damper D, the pipe-sections E and E, and the conduits formed by plates F-and F, substantially as and for the purpose herein specified.
